DON'T FORGET US, LITTLE BEAR

Little Bear is unhappy.
Winter has come much too soon, and he hasn't had enough time to play with his friends, a white rabbit and a gray rabbit. Very soon, he will have to hibernate.
The rabbits are also upset. They are worried that their friend the bear might forget them while he's hibernating. Well, the little bear must hibernate, but he doesn't want to forget about his friends!
The rabbits have the wonderful idea to play with the bear in his dreams so that he does not forget them. But how can they get inside the little bear's dreams? Maybe the wise old owl can help them.
